Demystifying LED Lightbulbs > 자유게시판

Perhaps you’ve already done the righteous factor and swapped out all your energy-sucking incandescents and not-universally-useful CFLs for long-lasting, mercury-free, power-saving LED bulbs. More likely, you’ve dropped in a number of here and EcoLight LED there, with mixed results. LED bulbs can nonetheless be chilly, alien-looking issues with odd shapes, splayed fins, and dazzling value tags. But they keep getting higher-and cheaper. In the event you haven’t already, now could be the time to start out making the swap, and we’re going to elucidate how and why. The first LED bulbs I tried made my living room appear like a hospital ward. How do I keep away from that stark white mild? Newer models do a greater job of diffusing the tiny directional beams that LEDs generate. But even so, you might want to start out with decrease-lumen (that means less shiny) bulbs. LED bulbs-which EcoLight home lighting electronic circuits and light-emitting diodes that act as semiconductors relatively than filaments-now are available in "color temperatures," including heat tones that can mimic incandescent bulbs and flatter furnishings, EcoLight akin to varnished wood.

Apparently, cooler ones are sometimes really useful for outdoors because they carry out the green in foliage, says Seattle-based lighting designer Christopher Thompson. There’s enough small print on the package deal to blind a lawyer. Search for the requisite Lighting Info label, which posts the Kelvin (Okay) ranking: EcoLight home lighting The nearer to the decrease finish of 2700K, the warmer the light (yes, that does sound backward). Bulbs are also rated for their capability to render coloration precisely, using what’s known as the Color Rendering Index (CRI). Incandescents, which do especially nicely with warmer colours, rating 100. You might must check the manufacturer’s web site for the CRI rating; despite all that small print, it’s not at all times on the package. I’m confused about watts and lumens. Life was so much simpler once i could replace one 60-watt bulb with another! Lumens are a greater method to compare brightness. Watts measure how much electricity a bulb attracts, not mild output, which varies, since not all 60-watt incandescents are equally efficient.

Extra essential, 60-watt-equal LED bulbs may seem brighter, since the light is cooler. So if you’re shopping for a 60-watt equivalent, EcoLight home lighting consider attempting a 40-watt equal as an alternative. Its 450 lumens could also be shiny enough. I love my recessed cans however can’t discover an LED flood that has a broad, EcoLight solar bulbs heat gentle. Search for a reflector bulb, such as the BR30 sort, with a slight bulge near the face of the bulb. Data on the package deal should say whether or not the bulb is a "spot" or a "flood," and may also embody the angle of the sunshine beam. In case you want a flood, search for EcoLight home lighting an angle of greater than 50 degrees or the acronym WFL, for large flood. Alternatives for recessed cans additionally embody LED surface-mount panel fixtures, corresponding to ones made by Pixi Lighting. One other problem: The dimmer is no longer capable of convey the sunshine method down. Conventional dimmers are often unable to operate LED bulbs: They might flicker or EcoLight home lighting fail to reply-a syndrome often called "dead travel." In different words, don’t assume a bulb labeled dimmable will jibe with the dimmer you’ve received.

Go to the bulb maker’s web site to see which dimmers go along with which bulbs-or seek the advice of the Lutron LED Control Middle of Excellence, which runs a toll-free hotline for pissed off consumers: 877-DIM-LED8. Smartphones might turn out to be the last word solution; Philips already makes bulbs whose colour and brightness are controlled by an app. Can I stick an LED bulb in any fixture? Pretty much. Simply match up your outdated bulbs’ bases with LED versions, taking care to additionally compare lumens, or brightness ranges (again, a lower-lumen bulb could also be extra pleasing). Some new bulbs are surprisingly good at mimicking the acquainted Edison, and one firm, Swap, has launched the primary three-method LED bulb. To soften the beam and make it much less direct, manufacturers set up multiple LEDs, reflectors, lenses, and diffusers inside the bulbs. Some bulbs look somewhat humorous until you flip them on or EcoLight put them behind a shade or inside a glass globe. But bear in mind that some LED bulbs cannot be used inside enclosed fixtures or capped recessed lights.

As Ray Johnston, a staff scientist at 3M, explains, LED bulbs have "heat sinks"-fins or one other manner out for the heat generated when power passes via the semiconductors-which help them use much less wattage and emit a lot less heat than incandescent bulbs do. But on the flip facet, LEDs are extra sensitive to their surrounding temperature and want a decent quantity of airflow to work well. Overheating won’t make a bulb explode, however it should shorten its life. As for chilly temperatures, unlike CFLs, LEDs do effective outdoors. How about replacements for unusual bulbs? Search for LED pin bulbs that may change halogens, small bulbs for candle-model fixtures, and specialized LED fixtures, EcoLight home lighting similar to undercabinet strip lights from firms like Kichler and Häfele and battery-operated lights for drawers and closets from the likes of GE and IKEA. Needless to say the aforementioned airflow situation has led to odd bulb shapes, EcoLight LED styles, and fin displays. Ask if the shop has a no-questions-requested return policy.
